Lead and coordinate end-to-end security incident management, including investigation, containment, eradication, recovery, and post-incident review. Direct root-cause analysis of sophisticated security incidents and targeted attacks across systems, networks, cloud environments, and application layers. Oversee tuning of security alerts to reduce false positives and increase operational efficiency; implement automated responses where appropriate. Partner closely with SRE, Cloud Security, IT Operations, Threat Intelligence, and other security teams to ensure timely remediation of identified issues. Manage SIEM strategy and operations, including onboarding new log sources, optimizing alert logic, and enhancing detection capabilities. Lead deployment and management of security monitoring solutions across all organizational environments. Guide and supervise threat-hunting initiatives to proactively identify malicious activity, suspicious behaviors, and emerging threats. Leverage threat intelligence, indicators of compromise (IOCs), and contextual data to enrich investigations and improve detection fidelity. Manage SOC-related projects, roadmap planning, team development, and operational execution. Champion the design and deployment of automated incident response workflows using SOAR and cloud-native automation tools to reduce analyst workload and accelerate containment. Implement automation playbooks that trigger predefined actions—such as isolating hosts, disabling compromised accounts, enriching alerts, or blocking malicious indicators—to improve response speed and consistency across the SOC. Evaluate emerging technologies, including AI-driven SOC analyst tools, and lead their implementation within the security operations environment. Minimum Qualifications Minimum of 8 years of experience in a Security Operations role, with progressive leadership responsibilities. Minimum of 3 years of experience in managing a team of Security engineers, analysts etc. Experience with security technologies including SIEMs, firewalls, IDS/IPS, EDR, and vulnerability management tools.

Deliver new high-fidelity detections and mature, actionable incident response playbooks for key attack scenarios. Ensure the SOC team is trained and aligned on newly implemented processes. 12-Month Accomplishments Achieve measurable reductions in Mean‑Time‑to‑Detect (MTTD) and Mean‑Time‑to‑Respond (MTTR) through strategic automation, improved workflows, and optimized tooling. Demonstrably improve the organization’s overall security operations posture by continuously enhancing detection logic, developing high‑fidelity alerts, and maintaining an up‑to‑date library of incident response playbooks. Successfully lead medium‑ and large‑scale projects aimed at strengthening security visibility, detection maturity, threat‑hunting effectiveness, and SOC operational excellence.
